Vermont Gage 112411750 Class Zz Minus Plug Pin Gage 11.75mm

Product Description

The VERMONT GAGE 112411750 is a Class ZZ Minus plug pin gage used for NoGo inspection of precision bore and hole diameters. Manufactured from steel with a 10 microfinish surface coating, this pin gage measures 11.75 mm in diameter with a tolerance of 0.00508 mm. At 2 inches in overall length and 0.1 pounds, it is sized for single-hand use in a bench or in-line inspection workflow. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for quality systems in machining, tooling, and metrology environments. Machinists, quality technicians, and tool-and-die professionals use this gage to verify that a hole does not accept an oversized condition.

This plug pin gage is designed for NoGo inspection tasks in precision manufacturing settings. It is well suited for use alongside set micrometers, vernier calipers, and other close-tolerance measuring devices in both production-floor and metrology-lab applications. The Class ZZ Minus designation indicates the gage is manufactured to a minus tolerance relative to the nominal diameter, making it appropriate for checking that bores remain within specified limits. It fits naturally into incoming inspection, in-process quality control, and final acceptance procedures wherever 11.75 mm bore tolerances are being held.

Key Features

• Class ZZ Minus tolerance classification for NoGo inspection of 11.75 mm diameter bores
• 0.00508 mm tolerance for close-tolerance quality verification
• 10 microfinish surface coating for consistent contact and reduced wear
• Steel construction for durability in production and metrology environments
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Compact 2-inch overall length suits bench inspection and in-line gauging setups

Compatibility

Designed for use with set micrometers, verniers, and other precision measuring devices requiring a Class ZZ Minus plug gage reference at 11.75 mm nominal diameter.

Installation Notes

Pin gages are handled and used by quality technicians and machinists and do not require mechanical installation. Store the gage in its protective case when not in use to prevent surface damage and contamination. Clean the gage pin and the bore being checked before use to avoid false readings from debris or oil. Do not force the gage into a hole; light hand pressure is the correct technique for NoGo gage application.
